Abstract
A table saw 10 includes a table 14 supported on a mount base 12, and a saw blade 25 rotated by a motor 22 and protruding upwardly from the table 14, so that a workpiece can be cut by the saw blade 25 as it is slidably moved on the table 14. In addition, the table saw 10 includes a cutting condition detection device for determining whether or not the workpiece is being cut, a vibration sensor 30 for detecting an acceleration of vibration, and a motor stopping device for stopping the motor 22 when the acceleration of the vibration detected by the vibration sensor 30 exceeds an acceptable value.
Claims15
A table saw, comprising
- a table supported on a mount base,
- a saw blade protruding upwardly through the table for cutting a workpiece as the workpiece slidably moves on the table,
- a motor for rotating the saw blade,
- a cutting condition detection device configured to be able to determine whether or not the workpiece is being cut,
- a vibration sensor configured to detect vibration,
- a motor stopping device operable to stop the motor when an acceleration of the vibration detected by the vibration sensor exceeds a predetermined value during the cutting operation of the workpiece.
A table saw comprising:
- a table;
- a saw blade;
- an electric motor constructed to rotatably drive the saw blade, so that a workpiece placed on the table can be cut by the saw blade;
- a vibration sensor operable to detect vibration applied to the table saw;
- a motor stopping device operable to stop the motor when an acceleration of the vibration applied to the table saw has exceeded a predetermined value.
